Effectiveness of MRI in Diagnosis of adenomyosis

Objective To investigate manifestations of adenomyosis on MRI and itseffectiveness as well. Methods MRI manifestations of 20 cases of adenomyosisconfirmed by both surgery and pathology were studied retrospectively. All cases underwentB-type ultrasonic examination and were compared with the postoperative pathologicalexamination. Results 16 cases were found diffuse adenomyosis, among them 3 caseswere complicated with hysteromyoma, displaying enlarged uterus, diffusely even oruneven thickening as thick as 12～43 mm in junctional zone. 5 lesions were found in 4cases of localized adenomyosis, displaying low-signal masses with blurred border againstsurrounding muscle layer. The masses were in muscle layer and had signal intensitysimilar to that of junctional zone. Conclusion MR imaging is a top non-invasivemethod for diagnosis of adenomyosis, and sagittal T2W/TSE is the best scan sequencefor displaying the lesions.[
